My users often receive emails (via Email-To-Case) which have additional recipients CC'd on them. But when the user responds to the email, from the standard (not custom) Case Feed Email Action, the CC field is not automatically populated and the additional recipients email addresses have to be manually entered.
Is it possible to automatically populate the CC field, with the email addresses of recipients of previous emails from the same Case?
Note: My users do have Service Cloud licenses and are using the Service Cloud Console.
The Customizing the Email Action documentation only lists the options for setting field level security for the CC field.
The SendEmailQuickActionDefaults Class documentation includes a getInReplyToId() method but doesn't mention the CC field.
While Emails will have a dedicated object after the Summer ,16 release, the Release Notes don't seem to suggest that the field will become accessible.
